Synopsis

Inquire about a code context, code model, or code result setting.

Syntax

MIL_INT McodeInquire(

MIL_ID ContextOrResultCodeId,	//in
MIL_INT64 InquireType,	//in
void *UserVarPtr	//out

)

Description

This function inquires about a setting of the specified code context, code model, or code result buffer.

Note that McodeInquire() in combination with McodeWrite() can also be used to determine the required image buffer size to encode a given string. First, call McodeWrite() with ImageBufId set to M_NULL and then call McodeInquire() to retrieve the minimum width (M_WRITE_SIZE_X) and height (M_WRITE_SIZE_Y) required for the code. This same method can be used to obtain the number of cells required to write your code (M_WRITE_CELL_NUMBER_X and M_WRITE_CELL_NUMBER_Y).

Note that this function reference has not been updated for a MIL system added during a MIL update. Refer to the MIL system's release note to see if there is complementary information.

Parameters

This function is not supported on the selected boards.

Parameters

ContextOrResultCodeId

Specifies the identifier of the code context, code model, or code result buffer.

InquireType

Specifies the setting about which to inquire.

See the Parameter associations section for possible values that can be specified.

UserVarPtr

Accepts the address of one of the following (see the Parameter associations section for specifics on which is expected):

MIL_DOUBLE
MIL_ID
MIL_INT
MIL_INT32

Specifies the address in which to return the value of the inquired setting. Since the McodeInquire() function also returns the requested information, you can set this parameter to M_NULL.
